There are no real issues - now in Kernel there are no users of GPD
which use "noirq" callbacks.
As of now, I'm trying to use GPD for Keyatone2, so
I'm studying it and playing with it to understand all benefits and
disadvantages of such solution.
So, I've found this issue, but not found any description of why
calls of these callbacks have been removed.
I'd very appreciate if can point me on?
